A density bottle of mass 14.5g.Weighs54.5g.When filled with liquid of density 1.3gram per cubic centimetre.Find the volume of bottle.If the density of paraffin is 0.8gram per cubic centimetre.What mass would fill the bottle?

the mass in the bottle is 54.5-14.5 g

now, you know that mass = volume * density
so just plug in your numbers

To find the volume of the bottle, we can use the formula:

Volume = Mass / Density

Given that the mass of the density bottle is 14.5g, we can substitute this value into the formula:

Volume = 14.5g / Density(bottle)

Next, we need to find the density of the bottle. The density of an object can be found by dividing the mass of the object by its volume. In this case, when the density bottle is filled with a liquid of density 1.3g/cm³, the total weight is 54.5g. We can subtract the weight of the empty bottle to find the weight of the liquid:

Weight(liquid) = Weight(total) - Weight(bottle)
= 54.5g - 14.5g
= 40g

Now, we can use this weight and the density of the liquid to find the volume of the bottle:

Volume = Mass / Density
= 40g / 1.3g/cm³
≈ 30.77 cm³

So the volume of the bottle is approximately 30.77 cm³.

Next, to find the mass that would fill the bottle with paraffin, we can use the formula:

Mass = Volume × Density

Given that the density of paraffin is 0.8g/cm³, we can substitute the volume of the bottle into the formula:

Mass = 30.77 cm³ × 0.8g/cm³
≈ 24.6g

Therefore, the mass that would fill the bottle with paraffin is approximately 24.6g.
